SPECIFICATION forming part of netter-s Patent No. 399,286, dated Marsh12, 1889.

Application ifiled August l0, 188th Serial No. 282,469. (No model.)

To @ZZ whom it 121.051/ concern..-

Be it known that I, ANDREW Il. Rossem.,

Aof the United States Army, stationed at Cin- Y beingof such form as tofit the receiver of a breech-loading'gun and maintailnthe. mirror atthe' proper angle, and also to hold the breechblock open. K

In the drawings l show thedevice applied to two forms of breech-loader.

- lt will readily be understood that by very slight changes theimplement may be used in anv common form of breech-loading gun.

igure l is a section through the receiver of a .Springiieldbreech-loader, showing a section of the reflector. Fig. 2 is a similarview of the receiver of a NVinchester magazine-gun, showing reflector inposition. 3 is a central cross-section ot the reiector. Fig. 4 is aperspective of same.

The reference-letter A designates the casing of my reiiector. Thiscasing is .preferably of thin metal struck up` or bent to approximatethe form and size of the interior of the receiver ofthe gun. The sidesmay be slightly flexible, so as to spring against the Walls ofthereceiver' and hold the implement in place. The form shown is thatpreferred for thezlSpringlield gun, and the material may be hard rubberor other substance instead of metal.

B indicates the mirror or reflector', which is secured in the casing Aat such an angle- (usually forty-five degrees) to the bottom or top ofthe casing that when the casing is in the receiver the mirror will be atan angle of about forty-live degrees with the axis of the bore. \\'henthe easing is rounded. at the bottom, as in the drawings, the mirrorwill be rounded to correspond. The mirror 1n the 55 plate, l'), securedto said block, and by points i illustration is supported by a woodenblock,

C, and is clamped in the easing by a bent ment from the receiver.

E, struck np in or cut through the metal of the casing A. A cross-bar,F, serves to snpport the upper corners of the casing, and also as ahandle or finger-hold to lift the imple- The casing and block may berecessed, as at G, to receive a retaining-catch or pass over anyprojection in the receiver.

For use in inspecting arms thc reflector is placed in the open receiverof the gun, and when pressed hone in the receiver will maintain themirror at an angle of about fortyiivedegrees with the axis of the bore.lhe casing should fit tightly enough in the receiver to retain theimplement in place, and will hold the breech-block open. 'lhe gun may beinspected fromthe breech by looking into the mirror, the line of visionbeing indicated by the dotted line, Fig. 2, or the gun. may beinspected. Afrom the muzzle, light being reflected into the bore in thedirection indicated by the same dotted line.

The instrument may 4be madeV in many forms. l`he'general idea is thatthe casing shall fit the receiver with suiiicient accuracy tomaintainthe mirror at .an angle ol' about forty-fi vc degrees with thebore, and shall-hold the breech open for inspection'.

lVhat l claim is l, A gun implement consisting oi aecasing or-lrame otsuch shape to lit the receiver of a gun, and a mirror held by saidcasing at the proper angle to throw light into the bore when the casingis adjusted in the receiver, substantially as described.

2. A gun implement consisting ot' a bent casing of such form as to fitthe receiver ol a gun and inelosing the sides of an inclined mirror, amirror, inclined as described, and clasps to retain the mirror inposition, substantially as set forth.

3. rlhe combination, in a gun implement, of a metallic casing shaped tolit the receiver of a gun, an inclosed mirror in said easingfretaining-catches for the mirror, 'and a iinger-piece or catchiorremoving the implement from the receiver, all substantially asdescribed.

:In testimony whereof l aliix my gnature in' presence of two witnesses.
